HINGE.

Application filed June 13, 1924. Serial No. 719,878.

To all whom it may concern: Be it known that we, JAMES MoGLnsnAN,

a subject of the King of Great Britain,

residing at York, in the county of York and State of Pennsylvania, andCARL Roniiirr Swnnson, a citizen of the United States of America,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in Hing-es, of whichthe following is a specification.

The invention relates to improvements in hinges, particularly adaptedfor mounting swinging windows or Windshields on stationarysupports,'but, of course, are applicable for use in various other fieldswhere such a type of hinge is found to be desirable.

It is an object of the invention to provide a hinge for automobileWindshields, and the like, having resilient friction means coaoting witha pair of relatively movable hinge members to permit a movablewindshield section to be engaged and adjusted at will, and to firmlyguide the same in its various positions of adjustment without manuallyloosening and tightening coacting hinge parts.

More specifically the invention comprises a hinge composed of a pair ofstamped out hinge sections of a light structure, each having a concavedface portion and fastening parts projecting therefrom on each side ofthe face portion, with an interposed star spring having a plurality ofseparated arms, the ends of which are adapted to alternately engage saidhinge sections to frictionally hold one section in any adjusted positionrelative to the other.

The invention further aims to provide an inexpensive hinge utilizingstamped out parts which may be assembled with ease, and which hinge,though inexpensive to manufacture, isexceedingly efficient in use.

In the accompanying drawings we have shown the preferred embodiment ofour invention, in which Figure 1 represents a view of the assembledhinge;

Figure 2 represents a view of the parts constituting the hinge in anunassembled condition; and

Figure 3 represents a detail view of the frictional star spring.

Referring now more particularly to the drawings wherein like referencecharacters indicate corresponding parts, the numerals 1 and 2 clesignatea pair of hingemembers which are of identical construction. These hingemembers are composed of struckout metal of any desired thicknessdepending upon the use to which the hinge isv to be placed.

Inasmuch as the hinge members are of the same construction a descriptionof one will apply equally to both and like reference characters willindicate similar parts in both of said nembers 1 and 2. Each hingemember is formed witha facing portion 3 that is concaved providingacavity therein forthe reception of a' frictional locking spring 4 to belater described. The concaved face portion of said spring memher isfurther provided with a series of spaced sockets 5 arranged in circularrela tion around said face portion near its periphery. These sockets arepreferably formed by the use of punches or the like, and are of anydesired depth. The shape of the sockets may-also vary, but it isexpedient that they be formed by means of a punch. The sockets can bespaced apart any desired distance, depending upon the fineness of'adjustmentthat a member supported by the hinge is to have. The faceportion also has a central pivot aperture 6 extending therethroughadapted to, receive a pivot bolt, rivet or the like by means of whichadjacent sections are united together withthe interposed frictionallocking spring. It is to be observed that the hinge section is formed ofa stamping having diametrically opposed arms 7 projecting outwardlytherefrom. These arms are formed with right angle flanges 8, each havingapertures 9 therein, said arms and flanges constituting attachingportions by means of which the hinge sec tions are united to a movableand a sta tionary part. From the description of the hinge section itwill be apparent that it is stamped out from a single piece of metal,that it contains no attached-or welded parts and it will furthermore beapparent that the two sections of the completed hinge areinterchangeable inasmuch .as said sections are of the sameconstruction.-

A pair of the sections that'have just been described are united by meansof the rivet 10, and interposed 'between said sections is. thefrictional-locking star spring 4:. This star spring is formed With acentral aperture 'txspanning the rivet 10 and is housed inthe spacebetween the faceportions 3 of the hinge sections due to the fact thatsaid face portions are concaved or dished. The star spring has aplurality of separated spring arms 11, six being shown for the purposeof illustration, inasmuch as the hinge members in this disclosure areformed with twelve sockets representing the different adjustments thatmay be obtained through thense of this'hinge. The spring arms 11 o'fthestar spring member radiate .i'rom'the body '12 thereof, and said armsalternately project .on opposite sides of said body'12. That is'to say,one spring a'rm extends to the right of said body whilethe next"succeeding =arm extends substantially .to the left, as clearly shownin- FigureQ; This means that the spring arms alternately.

v engage the opposed face portions of the adjacent hinge sectionsandfrictionally lock said sections against relative movement. To -obta1nsuch ailocking 21013101163011 spring armis provided near its outer endwith av stamped out protuberance 13 adapted to form a rounded head ineachspringarm to. engage in the sockets 5 provided in the'face ,portionsof each'hinge section. It is thereforeapparent that the spring arms areso arranged' that the rounded protuberances enterthe sockets in theadjacent'tace plates and lock these sections ifrictionally, against,relative movement. 'When the. desired pressure, however, is placed onthe windshield or other movable element one spring section, ofcourse,moves relative tothe other, compressing the springarms-and causing the,protuberances.atthe ends thereof to engage other sockets arranged inthe concaved face plates of said hinge members.

From the foregoing description of the partsaof the hinge, vit is thoughtthat its' .IOPBBltlOIliHld advantages. will be apparent,

butthe same may be-briefly recited as follows V Thejhinge is composed ofstamped out seetions, the twohingesections 1 and 2 being I. of 1 thesame construction and interchange able. .Theffaceportions, 3 of the?hinge members land 2'are dished and formed with aligned circular; rowsof socketsfi. The star spring eiis interposedbetween .said mem--,bve-rs. 1 and 2 within the enclosed space formed'by dishing the f'aceeportio'ns 3 of.

' eachlhinge. section. It will, be apparent that when oneof thehingemembers is turned this will compressor cause certain of the springarms1711 to yield and the rounded protuberances atthecnds thereof will rideout of. certainsockets in the hinge sections andente-r other sockets, ofcourse, retaining the movable'shield section in any one of its numbervarious ositions (of adjustment, :the positions 01" adjustment beingdetermined by the of sockets in each face portion.

, In operationit is, therefore, apparent that byengaging the shield and;applying cient stress thereto the shield can be sadjusted and the hingeis so constructed that vwh-en said shield is moved to any desired apivot passing through said hinge members 1 to unite them'together. v
